I could be wrong but I swear I heard that you're supposed to have a biopsy every 10,000mg.......I think that works out at like 7 years so having said that actually I think I could be wrong but I swear its after a certain amount of mg - if I didn't have a lecture to head off to I'd do a quick google! I've been on it 8 years though and haven't had one, blood and urine tests and check ups always perfect (touch wood!) I think it only gets done if really needed as its invasive.

I had a search and the advice seems to vary between 1.5 - 3g (I was wayyy off lol) to after 5 years of treatment, I guess it depends on how the bloodtesting goes and if the doctor thinks its necessary.

My doc didn't say anything about it. I sure hope not!!! I feel like I read that they used to do that, but I could be wrong.
